Usage of custom Factory Data Provider

FactoryDataProviderImpl is the default factory data provider. It is an extension of FactoryDataProvider K32W common class, which implements the following interfaces:

  • CommissionableDataProvider
  • DeviceAttestationCredentialsProvider
  • DeviceInstanceInfoProvider

A user can use FactoryDataProvider::SearchForId API to extract information about custom factory data ids.

What shall be done to enable usage of a custom factory provider in the reference app:

  • Set use_custom_factory_provider=1. This option is only available when factory data is used (chip_with_factory_data=1). An assert will be raised if the condition is not met.

  • Modify the BUILD.gn of the application to take into account the new files where the custom factory provider is implemented:

    if (chip_with_factory_data == 1 && use_custom_factory_provider == 1)
{
  sources += [
    "${k32w0_platform_dir}/common/CustomFactoryDataProvider.h",
    "${k32w0_platform_dir}/common/CustomFactoryDataProvider.cpp",
  ]

  defines = [
    "CHIP_DEVICE_CONFIG_USE_CUSTOM_PROVIDER=1",
  ]
}

Note that new flags were introduced:

  • CHIP_DEVICE_CONFIG_USE_CUSTOM_PROVIDER: add custom factory data related code in reference app.

Please refer to CustomFactoryDataProvider for a minimal example of leveraging the standard factory data provider to parse custom factory data information. Real applications could use the public API of FactoryDataProvider directly.
